VMware vRealize Operations Management Pack for Horizon | 17 FEB 2022 | Build 19307733

What's in the Release Notes

The release notes cover the following topics:


With the vRealize Operations Management Pack for Horizon, you can monitor the performance and capacity of the remote desktops and applications in the data center and managed services of Horizon.

vRealize Operations Management Pack for Horizon includes a broad set of simple to use but customizable dashboards to get you started with monitoring your VMware Horizon environment. Each set of dashboards is complemented with a series of out-of-the-box customizable alerts to further assist with your operational awareness. Each has a purpose and there is minimal overlap, as they form one continuum. It’s a way for the system to communicate with the user. Tasks that are performed through alerts, should be done through the dashboard to avoid Alert Storm. Reports should be kept minimal as they are not interactive and the information is not timely

Resolved Issues

  • MP4H fails to collect data due to java.util.concurrent.TimeoutException.

    This issue has been resolved.

  • MP4H data collection fails due to a case mismatch between provided Host URL and internal CS FQDN.

    This issue has been resolved.

  • MP4H metrics are not accurate when there is an Unmanaged Desktop pool with sessions.

    This issue has been resolved.

  • Helpdesk API Failures: Separating out collector timeouts and creating additional flags on the UI turns off certain metrics at runtime.

    This issue has been resolved.

  • ArrayIndexOutOfBounds Exception in VDIPool Metric Processor and RDS Farm Metric Processor.

    This issue has been resolved.

  • EventDB response time affects the duration of MP4H data collection.

    This issue has been resolved.

Known Issues

  • VDI Pool from other vCenter Server which share the same vCenter are taken into count

    When you have a Horizon Connection Server CS1 that has two vCenters registered as VC1 and VC2 and you have another Horizon Connection Server CS2 that has VC2 registered, then if you look at the dashboard, the VDI pool objects of CS2 are listed under CS1 Horizon Pod objects, which is incorrect.

  • Issues observed on Summary page of the Horizon adapter objects

    In the Summary page of the Application Pool Object, the performance across Sessions widget is empty. The summary page always shows No Data to display for all the Application pool objects.

  •  The objects in the Horizon adapter changes to the old data receiving state. 

     The objects in the Horizon adapter are in the old data receiving state. 

    Under the Advanced Settings of the adapter instance configuration page, set the Enable Login Metric Collection option to false. 

    Enable Logon Metric Collection is not recommended for Large Horizon environments. In large environments, the Horizon events database does not scale to MP4H requests. We recommend that users always disable this option and only enable it for specific user logon time troubleshooting.


  • Issues observed on DashBoard and Summary pages of the Horizon adapter objects.

    The Dashboard and Summary page of the Horizon adapter objects, shows No Data to display. For troubleshooting steps refer to https://docs.vmware.com/en/Management-Packs-for-vRealize-Operations-Manager/1.2.1/Horizon/GUID-7899E44D-E757-42F4-86EE-8B59E46F52B9.html
